So. EWI it is!!!! Now to discuss the pros cons and caveats of this, so that @kentar can be kept as a member here…..

Fast thumbs and lazy eyes. Oops 👀.

It’s an additive to prevent water freezing in an ASHP installation. Im struggling to see what would be sticky, that is leaking from the pump spindle.

What he said.

Yup. Best get the horse and the cart the right way around!

250mm insulation with 250mm concrete over it? EPS insulation? Then it looks like much thicker ring / intermediate beams too.

Depends on how far you let it drop before you catch it and start regenerating. This is referred to as “recovery” time btw. If it’s from cold mains from the street cold, there’s a huge amount of lifting that needs doing. If it’s from say 45° and back up, there’s a significant reduction in recovery time. This is why a lot of modern, larger UVC’s have a high and a low pocket for the temp sensors, as well as a standard socket for the generic cylinder stat. Means you have options to take better control over this in more demanding situations.

That’s leaking from the centre spindle, and the sticky goop may be Glycol? Is this heated by a boiler or a heat pump? The UPM3 is a very well regarded pump in the industry, so may just be a ‘Friday’ unit, or has been damaged by misadventure?

How much insulation have they proposed under the slab?

10mm pipes, and suspended / floating wooden floors? Have you any idea how the UFH was installed? In a pug / biscuit mix of sand & cement, or in aluminium spreader plates, or an overlay system (a-la Wunda)? Temp looks high, on the red (flow) side, so assume that the flow pipes are hot? Looks like 10-15 degrees differential, so you’re inputting heat into the floor, so more info please!

And why are you pushing back? Lack of head height?

What ICF product / system are you considering atm?

Happy days 🍻

You lazy bar steward.

100%. A true monoblock should be ready to rock and roll out of the box. Still very impressed with Panasonics J series stuff for the money. Crazy quiet and just a joy for its plug & play simplicity.

That’s excellent news However. Your advisory bill is now calculated at £7,366.00. Please send cash only. And don’t say anything to the others as I would rather they didn’t know

Yup. It’s doing an automatic “purge” of the air. One of WB more annoying features as when we were all tired and fed up after fitting the bastard things we had to wait for “it” to “decide” when we could go home lol. Sit and wait. Won’t be long !

Great perspective, thanks.

For wool yes, not heard of issues with EPS beads?

Spend the money blowing the cavities full of bonded beads. Very slim returns vs the time / money / disruption, and trying to make it look like it hasn’t been done. Of EWI isn’t done meticulously then you’ll be worse off than you are now. Lots of council done dwellings now complaining about huge damp issue; black walls / wallpaper peeling away etc. This is just not a candidate for a readily priced / achieved EWI installation, which you need to be able to justify costs vs ROI.

@Pt1987 👆👍

Pointless putting the solar in the shade?! Plus…. I was curious. 🧐. So “there”.

If it freezes, the joints all pop off everywhere and it loses pressure, ergo, it won’t start back up due to it then locking out.

It is now I’ve edited it ffs. This poxy phone writes what it wants to. (expletive deleted) my version off, why don’t you ?!?! Id be happy to go back to scratching this all into a bit of slate. Rant almost over ……

Yup. 👍. Put some jointing compound on the faces that meet together of the two parts, and a little on the threads. Joints should tighten smoothly, and not squeak like brass on brass does when dry. I’d drain down and take your time to do the repair. Prob only adds 2-3 hrs more messing around but a more relaxed job then
